Ghost hunting and the (lack of a) Scientific Method

Since I’ve been talking about the “science” of ghost hunting, I thought that now would be a good time to have a brief interlude and discuss how to do good science.

The scientific method is about creating a model of examined evidence or data, then trying out different hypotheses in order to attempt to explain what is going on. A good hypothesis makes predictions about the model that are testable, and the successes or failures of those tests are used in order to modify or even discard the hypothesis.

The biggest weakness with the scientific method is human bias. Good scientists try to guard against bias by setting up each experiment in a very careful manner, through peer review, and by being scrupulously honest in reporting any possible reason why their experiment might be fallacious.
